Package com.yahoo.config.application.api

Class DeploymentSpec

java.lang.Object

com.yahoo.config.application.api.DeploymentSpec

public class DeploymentSpec
extends java.lang.Object

Specifies the environments and regions to which an application should be deployed. This may be used both for inspection as part of an application model and to answer queries about deployment from the command line. A main method is included for the latter usage. A deployment consists of a number of steps executed in the order listed in deployment xml, as well as some additional settings. This is immutable.
